Moggaliputta-Tissa
Moggaliputtatissa (ca. 327–247 BCE), was a Buddhist monk and scholar who was born in Pataliputra, Magadha (now Patna, India) and lived in the 3rd century BCE. He is associated with the Third Buddhist council, the Mauryan emperor Ashoka and the Buddhist missionary activities which took place during his reign. Moggaliputtatissa is seen by the Theravada Buddhist tradition as the founder of "Vibhajjavāda", the tradition of which Theravada is a part as well as the author of the Kathāvatthu. He is seen as the defender of the true teaching or Dhamma against corruption, during a time where many kinds of wrong view had arisen and as the force behind the Ashokan era Buddhist missionary efforts. The Sri Lankan Buddhist philosopher David Kalupahana sees him as a predecessor of Nagarjuna in being a champion of the Middle Way and a reviver of the original philosophical ideals of the Buddha. Evidence from various Buddhist sources show that Moggaliputtatissa seems to have been an influential figure who lived during the time of emperor Ashoka. He is associated with the Third Buddhist councils and with the missionary work which led to the spread of Buddhism during the reign of Ashoka. He also seems to have been a staunch critic of certain Buddhist doctrinal views, mainly Sarvāstivāda (an eternalist theory of time), Pudgalavāda ("personalism") and Lokottaravāda ("transcendentalism"). Because of this, he is seen as one of the founders and defenders of the Theravada, which to this day rejects these three doctrines as unorthodox deviations from the original teaching of the Buddha Dhamma. Theravada sources state that with the aid of Moggaliputtatissa, Ashoka was able to purge the Buddhist Sangha of numerous heretics. Theravada sources, especially the Kathāvatthu, also explain these Buddhist doctrinal debates in detail. Bhante Sujato also notes how the Sarvāstivāda Abhidharma text called the Vijñānakāya contains a section titled the "Moggallāna section" which contains arguments against the theory of "all exists" from "Samaṇa Moggallāna".
